Regional Geology

This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

Early Miocene - Late Eocene
15.97 - 37.8 Ma



ID: 2914508
Oligocene nonmarine rocks

Age: Cenozoic (15.97 - 37.8 Ma)

Stratigraphic Name: Tom Thumb Tuff Member; Toutle Formation; Eagle Creek Formation; Ellensburg Formation

Description: Andesite conglomerate, tuff beds, and mudflow material. Includes some interbedded andesite flows in Columbia River Gorge. Lake sediments with Oligocene flora in Republic area in Ferry County. Massive tuffaceous sandstone and siltstone with beds of coal and high-alumina clay in Castle Rock-Toledo coal district in Cowlitz and Lewis Counties; include local interbedded basalt flows and some marine and late Eocene rocks.

Comments: Klondike Mtn Formation (in part: Tom Thumb Tuff Member); Toutle formation; Eagle Creek Formation; Ellensburg Formation (in small part); Includes very small outcrop in southern Stevens County which has been mapped as Gerome Andesite (note, however, that Stoffel and others, 1991, report that while the term "Gerome Andesite" was once widely used, it has since been abandoned). Some discrepancy over the lithology near Republic: Muessig, 1967, identifies the Tom Thumb Tuff Member as thin-bedded fine tuff while Stoffel, 1990, identifies it as primarily fossiliferous shale beds. The Eagle Creek Formation is almost entirely volcanic material: mostly andesite flows, tuff, and breccia, with some trachyte, trachyandesite, and basalt; lithology and stratigraphy suggests contemporaneity with Fifes Peak andestite (see WAOLMv) (Warren, 1941).
